Placing Test Calls

You can make a test call to 17771234567, or if you are signed up for one of Callcentric's rate plans you can place a call to a traditional landline or mobile phone by dialing either: 1 + the area code and number for calls to the USOr011 + the country code, area code, and number for calls worldwide (you may also use 00 instead of 011).
